Nitrogen (N) availability is a primary constraint to plant productivity, especially in marginal
lands with inherently low fertility. Root exudates change with plant nutrient status, and are …

Biological nitrogen (N) fixation (BNF) via diazotrophs is an important ecological process for
the conversion of atmospheric N to biologically available N. Although soil diazotrophs play a …

Perennial tall grasses show promise as bioenergy crops due to high productivity and
efficient nutrient use. Ongoing research on bioenergy grasses seeks to reduce their reliance …

Abstract Switchgrass (Panicum virgatum L.), as a dedicated bioenergy crop, can provide
cellulosic feedstock for biofuel production while improving or maintaining soil quality …

Root activity creates a unique microbial hotspot in the rhizosphere, profoundly regulating
free-living nitrogen fixation (FLNF). However, empirical assessments of rhizosphere FLNF …

Nitrogen-fixing microorganisms (NFMs) are important components of soil N sinks and are
influenced by multiple environmental factors. We established a random forest model …

Planting a cover crop living mulch between plastic mulch beds in fresh market vegetable
production can reduce soil erosion and runoff, and offers an opportunity to grow an income …

Maize/soybean intercropping systems are commonly used in developing countries, but few
studies have been performed to elucidate the differences in nutrient efficiency and …

The potential nitrogen-fixing bacterial diversity in the rhizospheric soil of the native
switchgrass (Panicum virgatum L.) from Tall Grass Prairies of Northern Oklahoma was …

Background Root and soil microbial communities constitute the below-ground plant
microbiome, are drivers of nutrient cycling, and affect plant productivity. However, our …
